论文摘要
令$(x,a)$是一个两极分化的非旋转曲线,3倍,无效$ a+k_x $。然后,对于$ x $上的任何足够的线条捆绑包$ l $ $ l $,由$ l $的完整线性系统嵌入的图像是四边形的一个交叉点。
Let $(X, A)$ be a polarized nonsingular toric 3-fold with not effective $A+K_X$. Then for any ample line bundle $L$ on $X$ the image of the embedding by the complete linear system of $L$ is an intersections of quadrics.
